The remote NewStart CGSL host, running version CORE 5.04 / MAIN 5.04, has thunderbird packages installed that are affected by multiple vulnerabilities:

  - Incorrect convexity calculations in Skia in Google     Chrome prior to 72.0.3626.81 allowed a remote attacker     to perform an out of bounds memory write via a crafted     HTML page. (CVE-2019-5785)

  - The type inference system allows the compilation of     functions that can cause type confusions between     arbitrary objects when compiled through the IonMonkey     just-in-time (JIT) compiler and when the constructor     function is entered through on-stack replacement (OSR).
    This allows for possible arbitrary reading and writing     of objects during an exploitable crash. This     vulnerability affects Thunderbird < 60.6, Firefox ESR <     60.6, and Firefox < 66. (CVE-2019-9791)

  - A flaw during verification of certain S/MIME signatures     causes emails to be shown in Thunderbird as having a     valid digital signature, even if the shown message     contents aren't covered by the signature. The flaw     allows an attacker to reuse a valid S/MIME signature to     craft an email message with arbitrary content. This     vulnerability affects Thunderbird < 60.5.1.
    (CVE-2018-18509)

  - Incorrect alias information in IonMonkey JIT compiler     for Array.prototype.slice method may lead to missing     bounds check and a buffer overflow. This vulnerability     affects Firefox < 66.0.1, Firefox ESR < 60.6.1, and     Thunderbird < 60.6.1. (CVE-2019-9810)

  - Incorrect handling of __proto__ mutations may lead to     type confusion in IonMonkey JIT code and can be     leveraged for arbitrary memory read and write. This     vulnerability affects Firefox < 66.0.1, Firefox ESR <     60.6.1, and Thunderbird < 60.6.1. (CVE-2019-9813)

  - When proxy auto-detection is enabled, if a web server     serves a Proxy Auto-Configuration (PAC) file or if a PAC     file is loaded locally, this PAC file can specify that     requests to the localhost are to be sent through the     proxy to another server. This behavior is disallowed by     default when a proxy is manually configured, but when     enabled could allow for attacks on services and tools     that bind to the localhost for networked behavior if     they are accessed through browsing. This vulnerability     affects Firefox < 65. (CVE-2018-18506)

  - Mozilla developers and community members reported memory     safety bugs present in Firefox 65, Firefox ESR 60.5, and     Thunderbird 60.5. Some of these bugs showed evidence of     memory corruption and we presume that with enough effort     that some of these could be exploited to run arbitrary     code. This vulnerability affects Thunderbird < 60.6,     Firefox ESR < 60.6, and Firefox < 66. (CVE-2019-9788)

  - A use-after-free vulnerability can occur when a raw     pointer to a DOM element on a page is obtained using     JavaScript and the element is then removed while still     in use. This results in a potentially exploitable crash.
    This vulnerability affects Thunderbird < 60.6, Firefox     ESR < 60.6, and Firefox < 66. (CVE-2019-9790)

  - The IonMonkey just-in-time (JIT) compiler can leak an     internal JS_OPTIMIZED_OUT magic value to the running     script during a bailout. This magic value can then be     used by JavaScript to achieve memory corruption, which     results in a potentially exploitable crash. This     vulnerability affects Thunderbird < 60.6, Firefox ESR <     60.6, and Firefox < 66. (CVE-2019-9792)

  - A mechanism was discovered that removes some bounds     checking for string, array, or typed array accesses if     Spectre mitigations have been disabled. This     vulnerability could allow an attacker to create an     arbitrary value in compiled JavaScript, for which the     range analysis will infer a fully controlled, incorrect     range in circumstances where users have explicitly     disabled Spectre mitigations. *Note: Spectre mitigations     are currently enabled for all users by default     settings.*. This vulnerability affects Thunderbird <     60.6, Firefox ESR < 60.6, and Firefox < 66.
    (CVE-2019-9793)

  - A vulnerability where type-confusion in the IonMonkey     just-in-time (JIT) compiler could potentially be used by     malicious JavaScript to trigger a potentially     exploitable crash. This vulnerability affects     Thunderbird < 60.6, Firefox ESR < 60.6, and Firefox <     66. (CVE-2019-9795)

  - A use-after-free vulnerability can occur when the SMIL     animation controller incorrectly registers with the     refresh driver twice when only a single registration is     expected. When a registration is later freed with the     removal of the animation controller element, the refresh     driver incorrectly leaves a dangling pointer to the     driver's observer array. This vulnerability affects     Thunderbird < 60.6, Firefox ESR < 60.6, and Firefox <     66. (CVE-2019-9796)

  - An integer overflow in path handling lead to a use after     free in Skia in Google Chrome prior to 71.0.3578.80     allowed a remote attacker to potentially exploit heap     corruption via a crafted HTML page. (CVE-2018-18356)

The version of Firefox installed on the remote host is prior to 66.0. It is, therefore, affected by multiple vulnerabilities as referenced in the mfsa2019-07 advisory:

 - A use-after-free vulnerability can occur when a raw pointer to a DOM element on a page is obtained using JavaScript and the element is then removed while still in use. This results in a potentially exploitable crash.(CVE-2019-9790)
 - The type inference system allows the compilation of functions that can cause type confusions between arbitrary objects when compiled through the IonMonkey just-in-time (JIT) compiler and when the constructor function is entered through on-stack replacement (OSR).This allows for possible arbitrary reading and writing of objects during an exploitable crash. (CVE-2019-9791)
 - The IonMonkey just-in-time (JIT) compiler can leak an internal JSOPTIMIZEDOUT magic value to the running script during a bailout. This magic value can then be used by JavaScript to achieve memory corruption, which results in a potentially exploitable crash.(CVE-2019-9792)
 - A mechanism was discovered that removes some bounds checking for string, array, or typed array accesses if Spectre mitigations have been disabled. This vulnerability could allow an attacker to create an arbitrary value in compiled JavaScript, for which the range analysis will infer a fully controlled, incorrect range in circumstances where users have explicitly disabled Spectre mitigations. Note: Spectre mitigations are currently enabled for all users by default settings. (CVE-2019-9793)
 - A vulnerability was discovered where specific command line arguments are not properly discarded during Firefox invocation as a shell handler for URLs. This could be used to retrieve and execute files whose location is supplied through these command line arguments if Firefox is configured as the default URI handler for a given URI scheme in third party applications and these applications insufficiently sanitize URL data. Note: This issue only affects Windows operating systems.Other operating systems are unaffected. (CVE-2019-9794)
 - A vulnerability exists where type-confusion in the IonMonkey just-in-time (JIT) compiler could potentially be used by malicious JavaScript to trigger a potentially exploitable crash. (CVE-2019-9795)
 - A use-after-free vulnerability can occur when the SMIL animation controller incorrectly registers with the refresh driver twice when only a single registration is expected. When a registration is later freed with the removal of the animation controller element, the refresh driver incorrectly leaves a dangling pointer to the driver's observer array. (CVE-2019-9796)
 - Cross-origin images can be read in violation of the same-origin policy by exporting an image after using createImageBitmap to read the image and then rendering the resulting bitmap image within a canvas element. (CVE-2019-9797)
 - On Android systems, Firefox can load a library from APITRACELIB, which is writable by all users and applications. This could allow malicious third party applications to execute a man-in-the-middle attack if a malicious code was written to that location and loaded. Note: This issue only affects Android. Other operating systems are unaffected. (CVE-2019-9798)
 - Insufficient bounds checking of data during inter-process communication might allow a compromised content process to be able to read memory from the parent process under certain conditions. (CVE-2019-9799)
 - Firefox will accept any registered Program ID as an external protocol handler and offer to launch this local application when given a matching URL on Windows operating systems. This should only happen if the program has specifically registered itself as a URL Handler in the Windows registry. Note: This issue only affects Windows operating systems. Other operating systems are unaffected. (CVE-2019-9801)
 - If a Sandbox content process is compromised, it can initiate an FTP download which will then use a child process to render the downloaded data. The downloaded data can then be passed to the Chrome process with an arbitrary file length supplied by an attacker, bypassing sandbox protections and allow for a potential memory read of adjacent data from the privileged Chrome process, which may include sensitive data.(CVE-2019-9802)
 - The Upgrade-Insecure-Requests (UIR) specification states that if UIR is enabled through Content Security Policy (CSP), navigation to a same-origin URL must be upgraded to HTTPS. Firefox will incorrectly navigate to an HTTP URL rather than perform the security upgrade requested by the CSP in some circumstances, allowing for potential man-in-the-middle attacks on the linked resources.(CVE-2019-9803)
 - In Firefox Developer Tools it is possible that pasting the result of the 'Copy as cURL' command into a command shell on macOS will cause the execution of unintended additional bash script commands if the URL was maliciously crafted. This is the result of an issue with the native version of Bash on macOS. Note: This issue only affects macOS. Other operating systems are unaffected. (CVE-2019-9804)
 - A latent vulnerability exists in the Prio library where data may be read from uninitialized memory for some functions, leading to potential memory corruption.(CVE-2019-9805)
 - A vulnerability exists during authorization prompting for FTP transaction where successive modal prompts are displayed and cannot be immediately dismissed. This allows for a denial of service (DOS) attack.(CVE-2019-9806)
 - When arbitrary text is sent over an FTP connection and a page reload is initiated, it is possible to create a modal alert message with this text as the content. This could potentially be used for social engineering attacks. (CVE-2019-9807)
 - If the source for resources on a page is through an FTP connection, it is possible to trigger a series of modal alert messages for these resources through invalid credentials or locations. These messages cannot be immediately dismissed, allowing for a denial of service (DOS) attack. (CVE-2019-9809)
 - If WebRTC permission is requested from documents with data: or blob: URLs, the permission notifications do not properly display the originating domain. The notification states Unknown origin as the requestee, leading to user confusion about which site is asking for this permission. (CVE-2019-9808)
 - Mozilla developers and community members Dragana Damjanovic, Emilio Cobos lvarez, Henri Sivonen, Narcis Beleuzu, Julian Seward, Marcia Knous, Gary Kwong, Tyson Smith, Yaron Tausky, Ronald Crane, and Andr Bargull reported memory safety bugs present in Firefox 65. Some of these bugs showed evidence of memory corruption and we presume that with enough effort that some of these could be exploited to run arbitrary code.(CVE-2019-9789)
 - Mozilla developers and community members Bob Clary, Chun-Min Chang, Aral Yaman, Andreea Pavel, Jonathan Kew, Gary Kwong, Alex Gaynor, Masayuki Nakano, and Anne van Kesteren reported memory safety bugs present in Firefox 65 and Firefox ESR 60.5. Some of these bugs showed evidence of memory corruption and we presume that with enough effort that some of these could be exploited to run arbitrary code. (CVE-2019-9788)

 Note that Nessus Network Monitor has not tested for this issue but has instead relied only on the application's self-reported version number.
